Abstract

The invention relates to a system and method for navigating an autonomous driving vehicle (ADV) that utilizes ADV an-onboard computer and/or one or more ADV control system nodes in an ADV network platform. The on-board computer receives sensor data concerning one or more occupants occupying an ADV and/or the ADV itself and, upon a detection of an event, automatically initiates a dynamic routing algorithm that utilizes artificial intelligence to re-route the ADV to another destination, for example a healthcare facility. One or more embodiment of the system and method include an ADV on-board computer and/or one or more ADV network platform nodes that utilize in-memory processing to aid in the generation of routing, health and navigational information to advantageously navigate an ADV.

Claims17

Dependent claims

An apparatus comprising:

one or more processors;
and
a memory having non-transitory instructions stored thereon that, upon execution by the one or more processors, causes the one or more processors to:
determine an occurrence of an emergency event associated with a vehicle;
determine a current geographical location of the vehicle;
identify, based on a determined type of the emergency event, a plurality of geographical artifacts to which the vehicle may be routed;
determine that a subset of geographical artifacts of the plurality of geographical artifacts is located within a predetermined maximum safety distance from the current geographical location of the vehicle;
select a first geographical artifact from the subset of geographical artifacts based on the first geographical artifact having a shortest temporal route from the current geographical location of the vehicle to a geographical location of the first geographical artifact;
and
send a control signal configured to cause the vehicle to navigate to the geographical location of the first geographical artifact.
